Default epoch for object RA / Dec
Does VPHOT assume a particular epoch for object coordinates during data entry?
I've experimented a little with J2000 and JNOW (e.g. 2011) when entering object coordinates. It seems that I get more plate solutions using J2000 rather than JNOW. Hence, I assume that the VPHOT default epoch is J2000.
My setup writes JNOW coordinates to the FITS header; hence, my interest in knowing which coordinates VPHOT actually uses. I've really enjoyed using VPHOT!
